分块法与轮廓积分法相结合分析Rotman透镜

Analysis of Rotman Lens Based on Segmentation Method and Contour lntearal Method

Rotman透镜馈电网络是产生多波束体制的一种有效手段，越来越多地用于雷达、预警系统和个人通信系统中。本文全面阐述了以分块法为指导思想，结合轮廓积分法分析Rotman透镜的过程，并详细叙述了利用分块法时的一些处理技巧，藉此可使计算量减少为原来的1／3。以上方法不仅可用于任意形状、任意无数、任意频率的Rotman透镜分析，还适用于Rotman透镜的计算机辅助设计。

The Rotman lens,an efficient multiple beamforming network, is frequently used in radar,surveillance and personal communication systems.The general procedure for the analysis of Rotman lens based on the segmentation method and the contour integral method is illustrated.Some new techniques are used to reduce the computation time greatly.The procedure presented here can not only be used to analyze the performance of any given Rotman lens,but also be suitable for the computer aided design of the optimization of Rotman Lens.
